As everyone else has said, definetely go back to the ENT. I wouldn't bother calling DAN because you need to go back to the ENT and they will be better able to diagnose you than a doc over the phone.
As for taking sudafed, 90% of the time it is the only way I can dive. Actually, now that I think about it I've done 3 dive days without it, and one of those was my first OW dive day and I sure wish I would have taken it. That being said if you are going to take sudafed take the 12 hour, not the 4. You might forget to take it after the first 4 hours like I did the last time I was out. I managed to clear but with a lot more issues than I normally have. There is also some debate about sudafed increasing your risk to CNS toxicity so if you're diving Nitrox you really shouldn't push your PPO2 level. If that last statement doesn't make any sense don't worry, you won't need to know about it until you start diving Nitrox.
